1.Globally, spring phenology and abiotic processes are shifting earlier with warming. Differences in the magnitudes of these shifts may decouple the timing of plant resource requirements from resource availability. In riparian forests across the northern hemisphere, warming could decouple seed release from snowmelt peak streamflow, thus reducing moisture and safe-sites for dominant tree recruitment. 2.We combined field observations with climate, hydrology, and phenology models to simulate future change in synchrony of seed release and snowmelt peaks in the South Platte River Basin, Colorado, for three Salicaceae species that dominate western USA riparian forests. 3.Chilling requirements for overcoming winter endodormancy were strongest in Salix exigua, moderately supported for Populus deltoides, and indiscernible in Salix amygdaloides. Ensemble mean projected warming of 3.5ºC shifted snowmelt peaks 10-19 d earlier relative to S. exigua and P. deltoides seed release, because decreased winter chilling combined with increased spring forcing limited change in their phenology. In contrast, warming shifted both snowmelt peaks and S. amygdaloides seed release 21 d earlier, maintaining their synchrony. 4.Decoupling of snowmelt from seed release for Salicaceae with strong chilling requirements is likely to reduce resources critical for recruitment of these foundational riparian forests, although the magnitude of future decoupling remains uncertain.

Boreal forests are facing profound changes in their growth environment, including warming-induced water deficits, extended growing seasons, accelerated snowmelt, and permafrost thaw. The influence of ...
The Tibetan Plateau is an important component of the global carbon cycle due to the large permafrost carbon pool and its vulnerability to climate warming. The Tibetan Plateau has experienced a noticea...
Mural cells in precapillary arterioles (PCAs) generate spontaneous Ca transients primarily arising from the periodic release of Ca from sarcoendoplasmic reticulum (SR/ER). The Ca release induces Ca-ac...
Numerous studies have treated the mass of a whole seed as an integrated unit, although the components seed kernel and seed coat play different roles and are subject to different evolutionary selection...
Aquaporins influence water flow in plants, yet little is known of their involvement in the water-driven process of seed germination. We therefore investigated their role in seeds in the laboratory and...
Two patient warming systems will be compared with 40 patients each in a convective warming group (BairHugger, Arizant) and in a conductive warming group (HotDog, Augustine Biomedical). ...
Intraoperative active warming is usually performed by skin warming. There are several forced-air systems on the market; forced air warming is generally described as the most effective yet ...
The aim of this study is to assess the effectiveness of EnsoETM as a supplemental warming device compared to the standard of care warming practice in patients having major surgery.
The purpose of this study is to determine if local warming of surgical wounds improves healing and helps prevent infection. The investigators want to see if warming surgical incisions impr...
The study examines the effects of delta-9-tetrahydrocannabinol (Δ9-THC), the principal active ingredient of cannabis, on neural synchrony. Neural synchrony is studied using electroencepha...
A methylpyrrole-carboxylate from RYANIA that disrupts the RYANODINE RECEPTOR CALCIUM RELEASE CHANNEL to modify CALCIUM release from SARCOPLASMIC RETICULUM resulting in alteration of MUSCLE CONTRACTION. It was previously used in INSECTICIDES. It is used experimentally in conjunction with THAPSIGARGIN and other inhibitors of CALCIUM ATPASE uptake of calcium into SARCOPLASMIC RETICULUM.
One or more types of plant seed proteins providing the large amounts of AMINO ACIDS utilized in GERMINATION and SEEDLING growth. As seeds are the major food source from AGRICULTURAL CROPS, seed storage proteins are a major source of DIETARY PROTEINS.
A subset of various vascular plants (also known as the Tracheophyta) which include seed-bearing and non seed-bearing species.
The state of failure to complete the process of GERMINATION of an intact viable seed, due to intrinsic physical, molecular, genetic, or physiological parameters under otherwise favourable prevailing conditions.
A repository of seeds maintained under optimal conditions that ensure long term storage, intended for use as a source of replenishment of seed stock or plant genetic material.
